IMPROVEMENT IN DOUBLE-ACTING FIRE AND RURGLAR ALARM TELEGRAPHSI Specification forming part of Letters Patent N o. 172,22 l, dated January 11, 1876 application tiled l January 29, 1873.

-To all lwhom it may concern:

r Be it known that I, WILLIAM B. WATKINS, ot' Jersey City, `State of New Jersey, have invented an Improved Double-Acting Heat and Burglar Signal Alarm 'lelegraph; and I do hereby declare the following to be a full description ot' the same:

.The nature of my 'invention consists, first,

ot' switches, circuit-closers, and an auxiliary circuit ot' galvanic electricity, having heat or:

burglar detecters arranged therein, whereby signals ot' lire or burglar' alarms at any point ot' the main circuit otl wires maybe Atransmitted through the apparatus and auxiliary circuit to the receiving signal-station, not` I withstanding that the main line of wires may be broken or short-circuited at any interme-l diate place between the' receiving signal-sta-` tion and magnet of the transmitting appa. ratus; third, in the method ot' combining, with" r a train ot' wheels, actuated by a magnet, av Yrevolving circuit-breaker, whereby signals i maybe transmitted either over a closed or open circuit, or both at the same time 5 fourth,

, in the method of automatically stopping the train of wheels by means of a self-adjusting i stop-lever, in combination with the armature and lever of an electro-magnet and a releasing-pin, operated by one Vof the train of wheels, whereby the train will be stopped when the current ceases through the actuatin g-magnet, with the revolving circuit-breaker wheel always in the same position with refer` ence to its metallic surfaces and spring cir-l cuit-breakers; tlfth, in the Inethod ot' operat-l ing a revolving circuit-breaker arm, secured c to the axis ot' a stationary circuit-breaker wheel by means of a stopping-lever, in combination with a iiywheel, detent-lever, and

adjusting switch-lever, `whereby alsignal is transmitted through the closed circuit of the main line to the receiving signalstation,l

I sixth, in the method of constructing a revolving circuit-breaker upon the periphery of the clock-work mainspring-barrel, in combination with two circuit-breaker springs, having an electric connection with an auxiliary branch of the maineircuit, whereby a detinite series ot' signals kmay be transmitted to any receiving signal-station; seventh, in the method of indicating the time when the train of clockwheels are run down by means of a toothed 4wheel, having a pointer attached to its axis,

and rotated by a stud or pin on the periphery of the uIainspring-barrel, whereby it maybe seen by simple inspection of the front of the apparatus when the mainspring requires winding up again, to insure its being in working order at all times; eighth, in the method of transmitting the sameV signalnumber by different means, by making the insulatingspa-ces across the face of a revolving circuit-breaker wheel of different lengths circumferentially ot' `the said wheel, whereby a fire or burglar ,alarm may be indicated by the longest insulating-space, while a signalcall, or other alarm, may be indicated by the shorter insulatingspace; ninth, in the method of completing the circuit ot' the auxiliary branch through the revolving circuit-closer 4wheel by ineans of an adjustable circuit-closer, in combination with two circuit-closer springs and theauxiliary branch circuit of the mainline, whereby either of the different signals or calls may be transmitted to the receiving signal-station, by the vibration of an adjustable switch t0 eitherside, to transfer the circuit to make the ditt'erent calls asdesired;v tenth, in the method of constructingadetective signal-call, by combining with the axis of the revolving circuit-breaker wheel, or other axis of the train ot' wheels` in connection therewith, a metal hub, having transverse .insulating-strip in- I serted inits` `face, and two circuit-closer springs at opposite 'sides of the hub, so arranged as to haverthe tip ot' one spring rest on theinsulator `and the other tip on thelmetallc portion of it, so as to form an open circuit through thesauxiliary circuit tothe receiving signalstation, but a closed circuit instantly that the Ahubrevolves, and thus woulddtransmit an alarm, should any one tamperwith the'train of wheels, though the circuits were open, through vthe fire or burglar circuit closers. i

- ]3ut,to'describe my improvements-more particularly, I will refer to the accompanying drawings forming'a part of this specification, the same letters of reference wherever they occur referring to like parts.

Fig. 2, Sheet 2, is a plan View of the apparatus and system of main and auxiliary circuits, and connectionsv with re and burglar circuitclosers, alarm instruments, and indicators. Fig. 3, Sheet 3, is a front view of the transmitting apparatus. Fig. 4, Sheet 3, is a detached view of the selfadjusting stop-lever and its connections. Fig. 5, Sheet 3, is a cut sectional View of the signalcircuit-closer wheel. Fig. 6, Sheet 4, isa rear view of the transmitting apparatus. Fig. 7,

Sheet 6, is a longitudinal cut sectional view of the apparatus through the line a: Fig. l. Fig. 9, Sheet 6, is a detached cut sectional view of the insulating-band as attached to the mainspring-barrel.

Letter A represents the base of the transmitting apparatus, and B the frame for the 4train of wheels to be secured upon. To the base are also secured an actuating-magnet, switches, and lines of wires for operating the apparatus. Letter C represents a receiving signal-station, at which is arranged a battery,

D, magnet E, and key F, From the positive pole of the battery a line, G, passes through the magnet E and key F, .and thence tothe screw-post H on the base A, button I, actuating-switchJ, vbutton K, switch L, and screwpost M, and thence returns to the station C,- and connects with the negative pole of the battery D, to complete a closed metallic circuit.

In connection With the receiving signal-station C is arranged an auxiliary branch circuit, N, magnet 0, battery P, and groundQ; also, at such points as may be desired, one or more other auxiliary branch circuits, R, magnets S, and ground T, may be combined with the metallic circuit Gr. The object of this combinationV of circuits is to obviate the objection to the use` of a simple metallic circuit, which, when once broken or short-circuited, cannot be used: for transmitting signals until it has again been electrically repaired. But, by my combination of the auxiliary branch circuit with the main circuit, two signals may be transmitted at the same instant over the' one wire to the receiving signal-station without interference with each other, While at the same time, ifa break or cross occurs at any part of the main line, the signal may still be instantly transmitted to the receiving-station without repairing the line.

The importance and utility of the combination of the auxiliary branch circuit with the main line will, therefore, be obvious, as itinsures perfect security against the spread of a fire before an alarm could be given at the receiving-station. f

Letters U, V, W, and X are representations of additionalauxiliarycircuits,branchingfromthe auxiliary'line R, which may connect with heatcircuit closers,as shown at Y and Z, for realarms; or with the circuit-closers a2 and b2 attached to doors or windows, for burglaralarms;' or with circuitcloser keys c2, d2, e2, and f2, in differentrooms, for signal-calls.

1n case of fire, the circuits W and X, when closed, may connect with the operating-magnet l(f2-of an indicator, h2, and with the auxiliary branch i2, for operating a train of wheels, (as is more fully described in certain other inventions made by me, and now on file in the Patent Oeel.) so that an armature, j2, will be released to let the train of wheels rotate, and by means of a dial-plate andpointer, k2, indicircuit will be transferred to an auxiliary branch, l2, screw-post m2, thence to a spring, n2, signal-circuitcloser Wheel, p2, of the tra-in of wheels of the transmitting apparatus, spring circuit-breaker o2, Wire q2, magnet S, and

thence through the ground Q of the auxiliary branch N, to complete the circuit with the station C, thus dispensing with the use of local batteries in the building.

In the auxiliary ground-branch t2 may be used a local-alarm-operating magnet, r2, and coil wz, of equal resistance, for dividing and maintaining the circuit, so that both the local alarm and the signa-1 at the station G may be given at the same instant. Asimilar indicator, m2, may be used in a similar manner for burglar-alarms when either of the circuits u or V may be closed, and the transfer auxiliary branch y2 from the indicator :v2 carried through the screw-post z2, sprin g circuitcloser a", to the revolving circuit-closer wheel p2, so

from the lire-alarm signal, and thus indicate the cause ofthe signal. t

It will be obvious that any suitable local alarm and indicator may be used to accomplish the objects described.

rlhe circuit breaker and closer springs n2 and a3 are secured to an insulator, b3, and separated from each other, as shown in Fig. 7, Sheet 5. Letters e3, d3, e3, f3, and g3, Figs. 1, 2, and 8, represent the axles or spindles of the train of wheels of the transmitting apparatus.

regulating the speed of the train of wheels; and on the axle e3 is secured a signal-circuit breaker and closer wheel, p2, which is insulated therefrom by a hub, i3, Figs. l and 7, and is in electric connection with the auxiliary branch circuit R.

The signal-circuitcloser wheel p2 may be arranged on the different instruments with such a number of breaks and such spaces between -them as may correspond with the signal-numto illustrate its operations to signal a given number-to Wit, No. 4, at the station C-four insulating-breaks, j 3, k3, Z3, andm, are used, Fig. 3.

cate the room on tire. At the same time the thence by the wire t2 to the ground l, and

as to convey a burglaralarm signal differing Ou the axle g3, Fig. 8, is secured a Hy, h3, for

ber desired to be transmitted. In this instance, v

It will be observed that when the circuiti closer wheel pzis revolved the circuit `will be open longer on j 3, Fig. 7 (when the circuit.l is completed through the circuit-closerspring n2) than it will be when the circuit is completed through the circuit-closer spring a3. `In either case the corresponding movements of the armature ofthe magnet O at the station C may be made to announce the cause of the signal 'by bringing. into operation`,tin a well-known l manner, any suitable printing, sounding, or in- 4dicating telegraph instrument; and, by connect; `inga localalarmcircuit `with the armature of the magnet O. a continuous alarm may be given at the `station C, should an accidental ground occur on theline G, and it will bc con tinuous until it is removed; thereby, by the special character of the alarm, as distinguished from the slower intermittentnumber-signals, becoming an automatic detective ot' any defect in the proper working condition of the line.

The magnet S is secured to the lower part `ot' the frame B ofthe transmitting apparatus,

and n3 is its armature, secured to the lower end of the leverro, working or vibrating on an axis, p3, Fig. 8. To `theiupper end ot' the lever a detent, g3, is formed, to holdthe liy h3 from rotating when there is `no current through the magnet, and is held in that position bya spiral spring, r3. s3 is an arm projecting from Aone side ot the lever 03, upon which rests one end ot' a stop-lever, t3, Figs. 3 and 4. This stop-lever is secured to the frame B by a center-pin, U3, so as to have ai'rre` upland-'down vibratory motion; and its object is to auto-` maticall y stop the train ot' wheels and revolving circuit-closer wheello2 always in the saine position, that the circuit breaker and closer springs n2 and ainay rest upon the metallic surfaces ot` the wheel p2, as shown in Figs. 3`

` and 7.` This is eli'ected by means ot' a cam,

r3. `or other equivalent device 'attached to the side of p2, (or its aXis,) as shown in Figs. 3 and 4, which, as the wheel rotates, depresses the inner end ofthe stop-lever t3, whereby the catchat its outer end is raised from the arm 33. \Vhen the armaturen3 is attracted bythe magnet S, or the lower `arm 'of the lever o3 is lotherwisc forced inward, the arm s3 will be withdrawn from the detent-notch in the outer end oi' the stop-lever t3. When thus released `the spiral spring x3attached to the lower side ot' the lever, will pullit4 down, so that `the catch at its outer end will again hold the arm s3 anddetent Q3, and the train of wheels wilt *be released, and the cani v3 will revolve in the direction ofthe arrow, as shown in Figsfi;` but when thecam rea-ches the position shlown in Fig. `3 it will depress" the inner end ot' the sto lever tia-nd cause its o i )osite or outer4 end to release againthe arm s3. It' at this point there is no current through the magnet S the armature lwill be released, and the train will be stopped by the detent-lever g3, with thecircuit-closer springs n and a3 resting up- 4on the metallic surface?)3 of the circuit-closer wheel p2 in theposition itrsthad, as shown, f lFigsand 17; `but it', in this :position of the `parts, there is still a current throughthe magnet S the` armature n3 will not be released, and the circuit-closer wheelp2 will continue to revolve until the circuit-closer which started .the train has been opened, thus repeating at eachrevolution of the Wheel at the station C the signal corresponding with the insulatingbreaks thereon. ai* is a switch, Working on a center pinor screw, b4, secured into the base A ofthe transmitting apparatus, and connects i with the `auxiliary branch R ot' the main .line Gr. This switch is held in position by pins c, but when pressed down may be turned on the button d4, connecting by a Wire with the circuit-closer spring a3, or on the button e, which connects with the circuit-closer spring n2. By this means the circuit maybe closed through either spring, as desired, to operate the instrument. f4 is an insulating-band surround ing the clock-work main spring-barrel, having spacesg, Figs. l and 9, cut through it at equal distances apart from each other throughout its length, so that the circuit-closer sprin gs h4 and i4 may make a metallic connection with the barrel as it revolves, but insulated therefrom Awhen resting on the band, as shown in Figs. l and `7. j, Figs. 1. and 2, is a wire, which connects the circuit breaker and closer spring h4 `with the groundwire T; and a wire, le", connects the circuit breaker and closer` spring "4 with the switch l, and the wire `m4 connects. the button n4 with the screwp0st 0.`

`When theswitch Z4 isturnedon the button n, and the .circuit has been closed through `either of the auxiliary branches, and the train ot' `wheels ot' the transmitting apparatus released by thevmeans above described, the `mainspringbarrel, with its insulating-bainlfi, will revolve until the ends ot' the circuit-breaker springs h4 and i4 press` upon the `metallic surface ot' the barrel through the opening y* in the band.` When this has been effected the trainwill instantly be stopped, as the circuitwill then be `completed through the path ot' leastresistance, which will be through the auxiliary branch R, wire m4, switchl, `wire` lo, springs "i4 anil h4,wire j, and then `directly in the dimeans described onlya delinite series ot' signals will ybe automatically transmitted at one l time, and the number may begoverned by the distance between theopen spaces g4 in the insulating-band f4. After the train has been stopped, as described,and the signals answered, the attendant may cause the springs h4 and i4 to rest on the insulating-band, `as shown in Fig. 7, by causing a single revolution ot' the circuit-closer wheel p2. For the purpose ot' showing-when the train is rundown, a spur, Q4, isat' -tached to the edge ot' the insulating-bandf",

der. The key a4, Figs. l and 2, connects with i the auxiliary branch R, and when pressed on the button c4 the circuit will be closed through the ground T, and messages may be transmitted to the receiving signal-station C, which will then be received by means ofthe magnet O of the auxiliary branch N, and without interfering with the operation ot' the magnet E-that is to say, both the closed circuit and the auxiliary branch circuits and magnets connected therewith may be used at the same instant without interfering with each other. The magnet @04, with its armature-lever x4 ot' the circuit G, is secured to the frame B of the transmitting apparatus. The lever x4 Works on an axis, y, and the spiral spring e4 and stop a5 regulate its movements. The stationary'circnit-breaker b5, Figs. 6 and 2, is secured to and insulated from the frame B. It has insulating-breaks in its face corresponding with those of' the revolving circuit-closer wheel p2, so as to signal the same number by means of electric connections through a vrevolving spring-arin, c5, secured to the shaft or spindle e3 by means of an insulating-hub, d5. The `spring e5, Fig-7, connects with the metallic portion ofthe circuitbreaker b5, andthe spring f5 connects with the revolving arm c5. Now, `when the switch J is turned in the direction ot' the arrow oli' the button K, Figs. l and 2, the` circuit will then be completed from the button l through the spring or key g5, wire h5, coils of magnet w4, Wire 5, spring e5, stationary circuit-breaker b5, revolving spring-arm c5,

springf, wirej, screw-post M, and thence tothe receiving signal-station C. Now,it will be obvious that it' the circuit G is in use the armature m4 will operate at intervals; but if not in use any desired message may be transmitted to the signalreceiving station C over the ciry cuit G by means ot' the key 7c5, which will opvcrate the spring-key g5 and the magnet VE at the station (5and thus, by the movements ot' its armature, bring into operation any of the well-known telegraphic instruments.

' The armature ot' the magnet E may also be f used to close a local-alarm circuit to notify the attendant, byringing an alarm, when a break occurs in the line Gr. Now, if it be desired to transmit a signal, the turning ot" the switch or-actuator J ot' the transmitting instrument in the direction of the arrow far enough, will push in the lower end of the lever 03, the arm attached thereto, s3, will be held back by the catch in the outer end ofthe stop-lever t3, when the train of wheels will be released and the spring-arm c5 will revolve around they stationary circuit-breaker wheel b5 and the magnetE of the closed circuit G, and instruments which may be connected therewith at the signal-station C will sound or Now, it' the switch L,'Fi0. 1, be turned on the lmtton a5, as shown in dottedv outlines,'the circuit will be completed through the wires o5 and i5, circuit-breaker b5 and connections, as described.. It' the auxiliary circuit B be now closed, by turning' the switch ai* on the button d4 or e4, or it' the circuit be closed through either of the branches Z2 or y2, Fig. 2, by the circuitclosers'Y, Z, a2, b2, c2, d2, e2, or f2, connected with these branches, the armaturen3 ofthe magnet s will be attracted, and the train will be released, and a double signal will be transmitted to the station C, operating the armature ot' each instrument located there, as has been described. lAgain, if the circuit Gr be broken, as at pointp, it would simply be divided into two open circuits, both connectedv with the auxiliary branch Nl and ground Q at the station (1 and then, it either of the branches l2 or y2, or the auxiliary circuit R be closed, as has been described, there will still be a signal transmit-ted to the station C by means 'ot' the revolving circuitbreaker wheel p2, and the signal will be received through the magneti 0 of the permanent auxiliary branch N at the station C,

without any attention t0 theline, and without repairing the break in the line; or, it` a cross should occur, as shown at g5, on the main line G, so as to cut out the circuit-breaker b5, and the auxiliary branches are operated, as has been described, the signal will still be given by means ofthe magnet the instant the circuit is closed.

lt will thus be evident that even when the closed circuit G is in use by another operator, it' the switch L is turned in the position as shown in the drawing, Fig. l, so that the circuit will not be completed through the stationar7 circuit-breaker b5, and either of the auxiliary branches V or U or R, b e closed by either `heator burglar detecters, as shown at Y Z, or azbz, or by turning the switch a4 on either of the buttons d4 or e4, as described, the signal will still be transmitted by means ot' 4the revolving circuit-closer wheel p2, and will' be received at the signal-receiving station G through the auxiliary branch N, without intert'ering with the working ot' thev circuit Gr. In all cases the signal through the auxiliary branches will be given, and will not be interfered with by operating the main circuit G. This is apparant from the fact that whenever the circuit is completed from any point'of thel A be to the right ot' N.

i auxilarybranch R through the ground'I, the -circuitmust be completed to the ground Q and through the branch N at the station C. Thebattery P generatcsthe current which operates the magnet O and its armature. This armature will not -be effected by opening and closing the-circuit G. It Will only be operated when the auxiliary branches are closed or broken, as described. The circuit will then be completed through the ground Q,

- and from branch N to the branch B. over the circuit G, ythrough the portion of least resist-` ance when the circuit G is closed. 1

When circuit Gr is broken, as at p5, and thus divided into two open circuits, as described, the only path for the current to branchR will It', with the break p5, the auxiliary branch T5 in building 8, Fig.`2, should f. be closed through the ground S5, the only path forthe current would be to the left of N, and both magnets O and E will operate their respective armatures in unison, as both batteries in this instance are 1n the circuit.

As a further explanation of the operations 'ot my improved system ot' automatically signaling tire and burglar' alarms, if the revolving circuit-breaker' 1o.z is stopped with the circuitl breaker spring a3 resting uponan insulatingspace, as ja, ot' said wheel, Fig. 3, and in this position the auxiliary branch It is permanently connected with i the spring a3 by securing the f switch a4 to the button d4, or otherwise, and *with the revolving circuit-breaker spring c5 resting on the metallic portion ot' thestationary circuit-breaker wheel b5, then by starting lthe train of Wheels With the actuator J, by i pushing in the` 4armature n3, both magnets U and E will operate at the station C, if the circuit Gr is closed; but it" it is broken or shortcrcuited, or both, then a signal will be given on the instrument ot' the auxiliary branch magnet 0, for, as has been previously described, when the revolving circuit-breaker "Wheel p2 revolves, and lthere is a circuit to `spring a3, there `must be alternate circuits `through the ground T. NOW, with the circuit-breaker spring fn? adjusted so as to be in `metallic contact, as at ys, Fig. 7, of the revolving circuit-breaker wheel p2, the signal' may be transmitted eitherautomatically by means of heat-detecter instruments,`or by means l Aof the switch J, regardless ofthe. condition of the line.

t5, Figs. 1 and 2, is a metallic hub, secured to and insulated from the axis 03, having an insulating-space a5 across its out operating any ot' the circuit-closers, (as

has been previously described,) will instantly transmit the signal, for immediately the train is started the hub t5 will be revolved, both springs @05 and 115 will then be upon the metallic surface of the-hub, and the circuit from the auxiliary branch R will be completed alternately through the signal-circuit-breaker wheel p2 and its connections through the ground T to the signal-station C. The signal Will be transmittedduring the revolution of the hub t5, upon whichever axis or spindle of the train ot' wheels it may be secured, and until the circuit is broken, when the insulatingspace a5 is again brought under the point of the spring g5. The object of this arrangement is to give a detective-signal when the"train of clock wheels is tampered with, also to be used to transmit a regular signal through the auxiliary branches by starting the train of wheels. i

It will be evident that the form of construction ofthe transmitter and its circuit-breaker and connections, and the manner of operating the same, may he varied in numerous Ways so as to carry out equally Well my invention ot transmitting signals by means of signaling instruments, in connection with open earth branches and a metallic circuit, having a permanent auxiliary earth-battery and receiving instruments connected therewith. l
